The other ends of t e toggle arms are ivoted res ectively to the sides of the cart body, as in icated at 40, to opposite-ends of the tail gate, as indicated at 41, and to lower arms 42 of the Z-shaped su porting members, as indicated at 43.

When t e control lever is given a downward 'ush so that it moves from the positionof ig. 1 to that of Fig. 2, the bell crank lever is thrown on its pivot 27 thereof moves rearwardly and causes the connecting bar to force the tog le arms to spread .from their positions in ig. 1 to their pos tions in Fig. 2. That is, arms 37 and 39 move from each other to tilt the cart body rearwardly, and arm 38 moves rear-wardly and Jforces the tail gate to turn on its pivot rear end of the body.

A coil spring 44 connected at one of its ends to arm 27 as indicated at 45, and at its other end to connecting bar 33, as indicated at 46, will return the cart body to its normal position when the control lever is released, as will be clear.

While a specific embodiment of the invention has been fully described, it is to be understood that such changes in details of construction and arrangement of parts may be made as fall within the scope of the appended claims.

What we desire to claim is:

1. In a dump cart of the character described, a cart body provided with a pivoted tail gate, a contro lever, a bell crank lever pivoted to the control lever and having a connecting -bar pivoted to it, and toggle and be swung from the arms pivoted to the connecting bar and to the sides of the cart body, to the tail gate thereof, and to fixed parts of the dump cart, respectively, whereby actuation of the control lever causes the cart body to tilt and the tail gate to swing on its pivot and away Jfrom the cart body.

2. A toy vehicle, comprising a at seat, a running gear, a pivoted cart body provided with `a pivoted tail gate, a control lever, and dumping mechanism extending between the cart body and control lever, said dumping mechanism comprising a bell crank lever, a connecting bar pivoted thereto, and toggle arms pivoted to the connectin bar and to the sides of the cart body, to t e tail gate thereof, and to fixed parts of the toy vehicle, whereby when the control lever is actuated the cart body is tilted and the tail gate is swung on its pivot and away from the cart body.

3. A toy vehicle of the character described, comprising a seat, a running gear, a pivoted cart body carried by the running gear and provided with a pivoted tail gate, a control lever, and dumping mechanism extending between the control lever, tail gate' and cart body, said dumping mechanism comprising a bell crank lever pivoted to the control lever, a connecting bar pivoted to the bell crank lever,` and toggle arms pivoted to the connecting bar, to opposite sides of the cart body, to opposite ends of the tail gate thereof, and to fixed parts of the toy vehicle.

In testimony whereof we aiix our signatures.
